Murrayfield - Corporate hospitality Dress Code

[BurblingBrownOne]

Going to Murrayfield on Sunday to watch Scotland put on another brave performance but likely get beat in the end due to self induced erros.
Anyway Im going as guest of corprotate hospitlaity package, whats the dress code?
Normally Id go to the stands in motheaten Kilt and rugger jersey, Im guessing this might be frowned upon in the suite?
Anyone been before, know the score? Im hoping it s not as stuffy as similar premiership football gigs where you have to be booted & suited.

Smart casual.
Kilt and rugby shirt would seem ideal.
